1. you have to leave the wheels there for a few days (not the car..no facilities)
2. don't expect a glossy showroom
3. the finish is not completely free of imperfections. If you want perfect, go to lepsons. But for £20 you really can't moan.
4. £20 is std silver finish. Other availiable too.
I'll shortly be taking my 968 to Rimtec in Meopham - not far from Lepsons in Gillingham but considerably cheaper. A member on here has used them before and was happy with the service and finish. Again it's leave the car with them for 3-4 days (they only charge £20 for this, Lepsons charge £48!), they chemical strip, bead blast, repair if necessary, powder coat and bake, paint then lacquer, refit tyres and balance - all for £210 including VAT for up to 18" wheels!
